This framing assumes something that hasn’t been demonstrated: that suffering is a variable God could simply “dial down” without fundamentally altering the structure of conscious life. Suffering is not optional add‑on, like background noise that could be reduced without consequence. This assumption is far from obvious.
People often imagine a world with “just a bit less” suffering, but the history of human psychology suggests that whatever the baseline is, we recalibrate. If physical pain, loss, or frustration were reduced to a fraction of what they are now, people would still experience the remaining discomfort as intolerable. Even trivial inconveniences, like boredom, social friction, unmet expectations, can escalate into deep psychological distress. So the idea that God could shave off some suffering while keeping everything else intact ignores how relative our experience of hardship is. Lower the floor, and we simply fall to the new floor.
I think the “optimum suffering” question is misguided. It treats suffering as a detachable quantity rather than a structural feature of beings who have desires, limitations, and the capacity to care about anything at all. You can imagine a world with no suffering, but imagination alone doesn’t show that such a world is metaphysically possible. I can imagine something coming from absolute nothingness, too, but that doesn’t mean it’s coherent. Mental conceivability is not a reliable guide to metaphysical possibility.
Also, I’m not so sure about those thinking agents that don’t seem to suffer. First, we don’t know whether they truly lack suffering or whether they simply lack the expressive channels we associate with it. Second, even if we could build a non‑suffering agent, that doesn’t show that a world of human‑like consciousness could exist without suffering. A thermostat doesn’t suffer either, but that tells us nothing about the requirements of a mind capable of valuing, choosing, loving, or experiencing joy.
I too believe that there is too much suffering in the world but I don’t think this feeling in itself can be used as an argument against the idea of a perfect deity (accused of inflicting gratuitous suffering).
